I looked and could find little information for this system. I will OPT OUT of your question and maybe another tech will have better info. If I find something I will post it here for you

Expert:  Jerry Newton replied 9 months ago.

Not to be overly obvious, but you did try hitting the button on the mirror first, yes?

There is a fuse for this, it is labeled ISRVM (inside rear view mirror), and it's located in the underhood fuse block. I would check that next, after verifying that it's not just turned off by pushing the mirror button.

I'll check both when I get home this afternoon. Sorry for the late response.
Expert:  Jerry Newton replied 9 months ago.

Not a problem, just let me know how this turns out, and I'll follow up with you.

ok so I checked the power button, no joy. checked the fuse, still intact. If it helps this was an intermittent problem for the last year but as of the last month it no longer comes on. If you have the wiring schematic (with colors) I can wring the wires.
Expert:  Jerry Newton replied 9 months ago.

I can do that.
